Slow progressive acceptance of intravenous thrombolysis for patients with stroke by rural primary care physicians.
Arch Neurol. 2007 Apr;64(4):518-21
Authors: Leira EC, Pary JK, Davis PH, Grimsman KJ, Adams HP
BACKGROUND: In the rural United States, patients with stroke are usually first evaluated locally by a nonneurologist physician (NNP) before treatment is determined. OBJECTIVE: To determine the evolution of NNPs’ familiarity and attitudes about using recombinant tissue plasminogen activator (rtPA) since this therapy has been approved. DESIGN: Cross-sectional design using 2 similar surveys mailed in 1997 and 2003 to all primary care, family, internal, and emergency medicine physicians in the state of Iowa (1582 and 1679 physicians, respectively). PARTICIPANTS: All NNPs (primary care, internal, and emergency medicine) practicing in the state of Iowa. MAIN OUTCOME MEASURES: Comparison of 1997 and 2003 aggregate responses to questions about familiarity and willingness to use rtPA to treat patients who have had an acute ischemic stroke. RESULTS: The willingness of NNPs to use rtPA to treat acute ischemic stroke increased from 18% to 32% between 1997 and 2003. The number of NNPs who were very familiar with the National Institutes of Health Stroke Scale increased from 1% to 13%. Compared with physicians in 1997, more physicians in 2003 knew that prolonged international normalized ratios (42% vs 61%) or excessively high blood pressures (61% vs 78%) were contraindications for the use of rtPA. Still, half of the respondents perceived that they were inadequately exposed to educational material about rtPA during these years. Most expressed preference for personal methods of delivery for future educational efforts. CONCLUSIONS: The familiarity and comfort among NNPs with the administration of rtPA is still relatively low in rural settings. The improvement observed between the years 1997 and 2003 is encouraging. The responses suggest that NNPs’ acceptance of rtPA can be further improved with educational campaigns involving personal methods of delivery.

The “Measuring Outcomes of Clinical Connectivity” (MOCC) trial: investigating data entry errors in the Electronic Primary Care Research Network (ePCRN).
J Am Board Fam Med. 2007 Mar-Apr;20(2):151-9
Authors: Fontaine P, Mendenhall TJ, Peterson K, Speedie SM
INTRODUCTION: The electronic Primary Care Research Network (ePCRN) enrolled PBRN researchers in a feasibility trial to test the functionality of the network’s electronic architecture and investigate error rates associated with two data entry strategies used in clinical trials. METHODS: PBRN physicians and research assistants who registered with the ePCRN were eligible to participate. After online consent and randomization, participants viewed simulated patient records, presented as either abstracted data (short form) or progress notes (long form). Participants transcribed 50 data elements onto electronic case report forms (CRFs) without integrated field restrictions. Data errors were analyzed. RESULTS: Ten geographically dispersed PBRNs enrolled 100 members and completed the study in less than 7 weeks. The estimated overall error rate if field restrictions had been applied was 2.3%. Participants entering data from the short form had a higher rate of correctly entered data fields (94.5% vs 90.8%, P = .004) and significantly more error-free records (P = .003). CONCLUSIONS: Feasibility outcomes integral to completion of an Internet-based, multisite study were successfully achieved. Further development of programmable electronic safeguards is indicated. The error analysis conducted in this study will aid design of specific field restrictions for electronic CRFs, an important component of clinical trial management systems.

Current diagnosis of venous thromboembolism in primary care: a clinical practice guideline from the American Academy of Family Physicians and the American College of Physicians.
Ann Fam Med. 2007 Jan-Feb;5(1):57-62
Authors: Qaseem A, Snow V, Barry P, Hornbake ER, Rodnick JE, Tobolic T, Ireland B, Segal J, Bass E, Weiss KB, Green L, Owens DK,
This guideline summarizes the current approaches for the diagnosis of venous thromboembolism. The importance of early diagnosis to prevent mortality and morbidity associated with venous thromboembolism cannot be overstressed. This field is highly dynamic, however, and new evidence is emerging periodically that may change the recommendations. The purpose of this guideline is to present recommendations based on current evidence to clinicians to aid in the diagnosis of lower extremity deep venous thrombosis and pulmonary embolism.
